Zumurrud Khatun Mosque and Mausoleum

The Zumurrud Khatun Mausoleum (Arabic: قبر زمرد خاتون, romanized: qabr zumurrud ḵātūn or Arabic: مرقد زمرد خاتون, romanized: marqad zumurrud ḵātūn), also known as the Tomb of Sitta Zubayda, is a mosque and shrine located in Baghdad, in the Baghdad Governorate of Iraq. The structure contains the tomb of Zumurrud Khatun, and dates from the Abbasid era. It is located in Sheikh Ma'ruf Cemetery in the Karkh side of Baghdad, and the site was built at the patronage of Zumurrud and her son. Zumurrud was the wife of the 33rd Abbasid caliph, al-Mustadi (r. 1170–1180) and mother of Caliph al-Nasir (r. 1180–1225). She collected the waqf money from madrasas and built her mausoleum, located in Karkh, before her death.

The building is covered by the distinct nine-layered muqarnas dome capped by a small cupola. The dome is considered to be the earliest surviving example of its type in Baghdad. The building has robust construction made of bricks and plaster. There is also an attached library, and an adjoined Shafi'i madrasa. Due to the mosque being dominated by Hanafi maddhab, the extension to the north for Shafi'i maddhab was added, which is called Shafi'i Mosque.
